Rear Air Conditioning Control Panel Circuit: Description

This circuit consists of the rear air conditioning control assembly and the air conditioning amplifier. When the rear air conditioning control is operated, signals are transmitted to the air conditioning amplifier through LIN communication.

If LIN communication malfunctions, the air conditioning amplifier does not operate even if the rear air conditioning control assembly is operated.
